I found some conceptual aged-up designs from an official concept art portfolio. Thoughts?
I was looking through character galleries on the Wiki when I found a link to his page. You might recognize other beta designs from there, like the gothic concept art for Splat or other characters from the games developed by Vicarious Visions.
Ninjini and Tree Rex don’t have the “growing up” label but the former of the two is shown next to Hex and Stealth Elf in a later image, and Tree Rex is referred to as “next” which could be interpreted in a few different ways.
Ofc it’s been nearly a decade since the series died and this didn’t go anywhere but these concept designs are really intriguing. Gives me inspiration as a fan to see a community-made sequel series one day.
